An enqueued message can only be removed from its queue by the dequeue command, and only after the DQTIME time delay (if any) elapses. The reply to this message is put in the REPLYQ-specified reply queue or, if this option is omitted, in the reply queue specified in queueName's JIF definition. enqueue can also specify a failure queue to supersede the one specified by the JIF. You can prevent reply and failure queueing with the NOREPLYQ and NOFAILUREQ options, respectively.
